Title: Improvements in rubber vulcanisation and in the manufacture of accelerators therefor
IPC: C08K5/00
Filed: 1931-03-04
Abstract: In the manufacture of vulcanization accelerators of the aldehyde-amine condensation product type the aldehyde used is one which contains more than one carbon atom and which has been stabilized, shortly after its formation and before its reaction with the amine, by the addition of an amine which is an antiager for rubber.  Specified aldehydes are acetaldehyde, butyraldehyde, and crotonaldehyde and specified stabilizing amines are phenyl-b -naphthylamine, b  : b -dinaphthylamine, m-tolylenediamine, diaminodiphenylamines such as 2 : 4-diaminodiphenylamine, and aniline.  The stabilized aldehyde may suitably contain about 2 per cent of the amine.  The aldehyde-amine, e.g. aldehyde-aniline, condensation products obtained from the stabilized aldehydes are stated to be more uniform in their properties than those obtained from the unstabilized aldehydes, and examples are given of vulcanization tests using crotonaldehyde-aniline condensation products obtained from (1) unstabilized crotonaldehyde, (2) crotonaldehyde stabilized with 2 per cent of b  : b <1>-dinaphthylamines.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use, for stabilizing the aldehydes, of any antiager for rubber and further specifies for this purpose b -naphthol, hydroquinone, and methylenedi-b -naphthol.  This subject-matter does not appear in the Specification as accepted.ALSO:In the manufacture of vulcanization accelerators of the aldehyde-amine condensation product type, the aldehyde used is one which contains more than one carbon atom and which has been stabilized, shortly after its formation and before its reaction with the amine, by the addition of an amine which is an anti-ager for rubber.
